A bit unusual keris

[Raja Muda]

While we're on this subject, there's always one thing I wanted to ask Dave. Last month I visited the Asian Civilisations Museum across the bay from the Cavanagh bridge.
I was intrigued to see one of the kerises in the display. It has a nogo blade if I'm not mistaken but it was provenanced Bugis (again, if memory serves me right). I don't know if anyone else here, especially the orang Singapure have ever noticed this particular blade (inside the Malay world gallery).
Were the Bugis smiths also manufacturing blade types similar to those by the Javanese empus or was this one a trade blade? hmmm
